Review Eufy RoboVac 11S robot vacuum cleaner: functional, but what about connectivity? [análise/vídeo]

O RoboVac 11S is a Eufy robotic vacuum for simple daily cleaning. It doesn’t wipe around the house like the Samsung POWERbot-E nor does it have a dedicated application for programming like the Roomba e5, from iRobot. Even so, the Elfy device can sweep, vacuum, has a remote control with various programs, a fall sensor and intelligence to clean carpets and rugs without too many difficulties.

In the Brazilian market, the device can be found for around R$ 2 thousand. Is it worth paying all this for the gadget? And, of course, how is your performance in residential cleaning? Over the past few weeks, I’ve had the opportunity to review the Eufy RoboVac 11S and I’ll tell you all its good and bad points in this review.

Eufy RoboVac 11S is the same as other robot vacuums on the market and identical to RoboVac 11, which is older. Without buttons and LEDs on top, the device has a simpler and less “modern” design. It is round and built entirely in darkened plastic, which appears to be quite resistant — fortunately, during the work, the equipment did not get scratches and dents after clashing with chairs, doors, walls and tables.

At the top there is only a single button that serves as “play/pause” to start or stop cleaning in place. At the bottom are the main switch to turn the robot vacuum on and off, the rechargeable battery compartment and the dust collector. I’ll start by talking about the vacuum cleaner’s deactivation button, which, although it didn’t cause a bad user experience, would be better to put it in another position, so you can turn it on and off quickly and without getting your hands dirty.

The front area houses a kind of bumper to “hide” the device’s sensors. Underneath there are also other sensors that help the gadget during cleaning. One thing I liked about the Eufy RoboVac 11S is that, even though it’s a simple device, it has a fall sensor and it didn’t crash after finding a ladder and other obstacles, automatically looking for another route.

Cleaning

A rotating brush at the bottom and two others at the end of the equipment are responsible for all cleaning of the environment. The first component’s mission is to collect and store the dirt in the dust collector, while the other brushes rotate to facilitate this work of collecting and sending to the rotating brush, accessing peripheral points. Looking at performance, the Eufy RoboVac 11S is very competent for vacuuming hair, cat fur, small papers and crumbs.

It has three suction modes. Standard operates around the house doing a simple cleaning; BoostIQ is icing on the cake and changes suction power according to the floor automatically; finally, there is the Max mode, which is the maximum power. In tests, the Standard was enough to eliminate dust on the floor of my apartment. The other configurations, useful in carpets and rugs, worked well and the RoboVac 11S was successful in eliminating dirt that was in the smooth carpet, but when accidentally passing through a carpet with high hair, the device could not stand it, called for help and even damaged one of the brushes.

As I assessed performance, two things caught my eye. The first observation is that the vacuum is very quiet and, at full power, with the help of an Apple Watch, it recorded an average of 68 decibels on a conventional tile floor — at no time did the noise bother me. The second point is the accuracy of the sensors. It was good to see that the Eufy RoboVac 11S doesn’t clash all the time with doors, dressers, chairs and tables — even people and animals the technology recognizes. Of course, these sensors are not 100% reliable and you can’t send a tap here and another there. Also, it can happen that he gets stuck because of an obstacle in the way. Still, detection most of the time works correctly.

Connectivity and autonomy

I think the main downside of the Eufy RoboVac 11S is the lack of connectivity features. Unlike other robot vacuums, the model rated by Techblog has no application and all configuration must be done by remote control. In it you will find options for the RoboVac 11S to act at a specific point in the house, you can adjust the operating time, it is also possible to program it to come into action when you are on the street, among other features.

There is a button that automatically returns the gadget to the docking station. This is a system that will always impress because it is a bit “futuristic”, but sometimes the robot is a little slow to return to the accessory after you trigger the command. At one point, with the base nearby, he insisted on cleaning a room he no longer needed.

In terms of autonomy, the company says in its communication that the robot can work for up to 100 minutes and when the button on top turns orange, it means that the battery is near the end of its life. In the tests of the Techblog, with the Max mode activated and cleaning all the rooms in the apartment, the RoboVac 11S remained on for 1h54min, a good time considering the suction power.

Robot vacuum cleaner Eufy RoboVac 11S: is it worth it?

With a good cleaning performance, the Eufy RoboVac 11S is a robot vacuum that can be worth your while. I want to commend Anker, owner of the Eufy brand, for developing a product with such a simplified user experience. Everything here is easy: configuring, changing accessories and putting them to charge are uncomplicated tasks that even lay users will master on the first day with the device at home. Of course, despite these strengths, it can’t be said that the vacuum cleaner is effective in heavy cleaning, when, in fact, it can be a complement to this type of cleaning.

With that in mind, the device should please many people. During the days I was testing the Eufy RoboVac 11S on Tecnoblog, I could see that the device can clean the environment well, removing pieces of paper, hair, animal hair, etc. But what makes me most disappointed with the product is the lack of a connectivity system. A simple app with basic features would be enough. I confess that it was strange to put the robot in operation without knowing how much charge it had, for example.

Another hurdle is the retail price for a robot vacuum that belongs to the entry-level category and has basic functions. In my opinion, it’s not worth spending more than R$ 2 thousand for the Eufy RoboVac 11S, but if you find it for less than that, it might be a good idea to consider this option.
